Description
(Chloromethyl)dimethyl(4-vinylphenyl)silane (CAS 17342-57-3), molecular formula C11H15ClSi and molecular weight 210.78 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine substitution, an aromatic ring system, (Chloromethyl)dimethyl(4-vinylphenyl)silane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 210.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (Chloromethyl)dimethyl(4-vinylphenyl)silane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
